Question

I have a simple (obfuscated) class:

public Thing ()
{
    public IList<string> Strings()
    { 
        // returns an IList of whatever, 
        // using strings as an example
    }
}

elsewhere in my code I retrieve an IQueryable<Thing> things from the database

My goal is to get all of the strings from the things into one IQueryable<string> strings, perhaps something like:

var strings = from t in things
              select t.Strings()

but that only gets me an IQueryable<IList<string>>. How do I mush all of those lists into one all-encompassing collection?

Answer 1

try using something like:

things.SelectMany(t => t.Strings);
